Analysis Of Milling Mechanism By Ball End

Nov 01, 1988 We analyzed the milling mechanism of a typical Ball End-Mill used for die-sinking and performed cutting tests. As a result, we have achieved high speed and fine quality die-sinking technology. Its feed speed is about four or five times as fast as before, and the irregularity of the milled surface is under one-fifth as compared with previous level

    Analysis of Cutting Mechanism by Ball End Mill Using 3D

    This paper deals with an analysis of the chip area by ball end milling of an inclined surface using a contour path method. At first, the modeling of a cutter, an edge, a rake surface and a workpiece with an inclined surface are carried out using 3D-CAD. Secondly, the chip area is calculated by the interference of the rake surface and the chip volume

    Abstract: In this paper, cutting mechanism and cutting performance of ball end mill for spherical surface with contour path method is investigated. Ball end mills are used to produce molds, dies and so on. However, the edge shape is complex, so cutting process is not clear. Then, it is not clear effectively using method of the tool based on good cutting performance

    Mechanics and Dynamics of Ball End Milling | J. Manuf. Sci

    Nov 01, 1998 The helical ball end mill attached to the spindle is modelled by orthogonal structural modes in the feed and normal directions at the tool tip. For a given cutter geometry, the cutting coefficients are transformed from an orthogonal cutting data base using an oblique cutting model. The three dimensional swept surface by the cutter is digitized using the true trochoidal kinematics of ball end milling

    This article presents the tool wear mechanism when machining Aluminium alloy 6061-T6 with PVD coated carbide under dry cutting condition. Cutting parameters selected were cutting speed, Vc = 115-145 m/min; feed rate fz = 0.15-0.2 mm/tooth and depth of cut, ap = 0.5-0.75 mm. The result showed the tool life of PVD TiAlN ranged from 11 to 97 min. Full factorial approach was employed to exhibit

    Sep 01, 1996 The linear flank edge force components, which constitute a significant part of the total forces in ball-end milling close to the ball tip region, are modelled and separated from shearing forces. The model is verified by conducting over 60 ball-end milling tests at different feeds, speeds, axial and radial depth of cuts and bail-end mill geometry
